AI Technical Summary

Technical Problem

In existing technologies, using high-frequency sound waves or electrolysis of seawater to kill marine organisms can only remove some of them and have little impact on the platform. It is also impossible to actively clean up existing marine organisms or silt, requiring divers to clean them regularly, which is labor-intensive.

Method used

A cleaning device for the legs of an offshore oil platform was designed, comprising a cleaning unit, an attachment unit, and a power unit. The cleaning unit removes marine organisms using a vibration device and a cutter head. The attachment unit is attached to the legs using permanent magnet tracks. The power unit is driven by a motor and a pneumatic/hydraulic cylinder. The control unit is operated with the assistance of a camera.

Benefits of technology

It enables automatic cleaning of marine organisms on the legs without the need for divers, reducing labor intensity, improving cleaning efficiency, and reducing marine organism corrosion on the legs, making it suitable for multi-environment platforms.

Abstract

The utility model provides an offshore oil platform pile leg cleaning device, and relates to the technical field of ocean engineering. The removing unit is arranged at the front end of the main body and is used for removing marine organisms; the control unit is connected with the main body and comprises a controller; the attachment unit is connected to the bottom of the main body and comprises a permanent magnet track; the power unit is electrically connected with the control unit and comprises a first power unit used for driving the permanent magnet crawler belt and a second power unit used for driving the clearing unit. The device is small and flexible in overall structure, high in adaptability, capable of effectively reducing pile leg marine organism removing difficulty and reducing corrosion and influence of platform pile leg marine organisms on the pile legs, suitable for periodically removing marine organisms attached to the pile legs all year round, capable of being used in different environments of multiple platforms and high in practicability. And meanwhile, the labor intensity of people in the pile leg marine organism cleaning process can be reduced, and great application and popularization value is achieved.
